C. G. CONOVER, OF JEFFERSON, WISCONSIN.

SHINGLE-MACHIN.

Specification of Letters Patent No. 24,445, dated June 21, 1859.

To alZ whom if may concern:

Be it known that I, C. G. CoNovER, of Jefferson, in the county of Jefferson and State of lVisconsin, have invented a new and Improved Shingle-lVIaeliine; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a longitudinal vertical section of my invention taken in the line 0c, Fig. 3. Fig.` 2, is a transverse vertical section of ditto, taken in the line y, y, Fig. 3. Fig. 3, is a horizontal section of ditto, taken in the line e, e, Fig. l. 4 v

Similar letters of reference indicate corresponding parts in the several figures.y

This invention relates to certain improvements in that class of shingle machines in which the shingles are rived or cut from the bolt by means of a reciprocating knife, and has for its object the riving of the shingles from the bolt, the tapering of them in proper form and also the jointing of them by a novel automatic mechanism which will be hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a rectangular frame which may be constructed in any proper ways to support the working parts of the machine.

B, is a driving or power shaft, placed in the front part of the frame A, .and having six'wheels c, c, b, b, c, c, placed on it as shown clearly in Fig. 2. The wheels a, w, are toothed entirely around their peripheries, but the wheels b, b, c, c, have their peripheries but partially toothed. In the frame A, a shaft C, is also placed, said shaft being parallel with the shaft B, and having the same number' of wheels on it as shaft B, said wheels being toothed in precisely the same way as those on the shaft B, but placed in a different position on their shaft as shown in Fig. l of the drawings, in which Fig. l, represents the teeth of the wheels Z9, b, on shafts B, .and C, said teeth being in outline, and Fig. 2, represents the teeth of the wheels c, and its fellow c, on shafts B and C, said teeth being partially shaded. The wheels a', a', on the shaft C,

- the teeth of which are designated by the iigure 3, and are tinted black, gear into wheels D, D, which are placed in the upper part of the frame A, and have each two cams ZZ, cZ, on their innersides, the form of which cams is plainly. shown in Fig. 3. The camsv CZ, (Z, act against horizontal slides e, e, c', e, placed in the upper part of frame A, and between the wheels D, D, the slides e, c, being at the lower parts of thewheels D, and the slides e', at the upper parts, see Figs. l and 2. Io the inner endsof the slides e, c', vertical knives E, E, are secured, and between the upper and lower parts of said knives, springs f, are placed, saidv springs having a tendency to keep the knives E, E, distended, see Fig. 3.

In the-frame A, and directly in front of the knives E, E, two vertical plates g, g, are placed. These plates have a certain degree ofl elasticity and may be formed of metal-steel being preferable. On the frame A, a vertical bearing plate or fence F, is placed and permanently secured.

G, is a carriage which is placed on the frame A, between guides h, h, said guides being secured transversely on the frame and at the right side of the fence F. The under side of the carriage has a rack H, attached to it, which rack is provided with oblique teeth (LX, the position being shown by dotted lines in Fig. 3. To one end of the driving or power shaft B, an arm I, is attached, which arm gears or engages with the rack H, at every'revolution of shaft B. On the upper part ofthe frame A, two sliding racks J, J, are placed, to the back ends of which a clamp K, is attached. This clamp is formed of two jaws z', z', which are attached to the horizontal bars y', y', which are' tted in proper guides 7c, 7c, attached lto a plate Z, said plate being attached to the racks J, J. Between the two jaws z', a spring m, is placed, said spring having a tendency to keep the jaws z', i, distended and the outer ends of the bars j, y', against plates 7c', Z0, the inner surfaces or sides of which are recessed at each end as shown at Z. On the upper part of the frame A, there are also placed two sliding racks K, L, to one of which K, a plate or carriage M, is attached, said plate or carriage working on a suitable way or guide m', and having an upright N, attached to it, said upright being in line with the plates g, g, and knives E, E, as shown clearly in Fig. 3. To the rack L, a vertical knife O, is attached. Into the racks J, J, the wheels b, Z7, b, b', gear alternately,

Directly back of the knives E, E, there are i placed in a suitable support fn., a series of cutters o. These cutters when not otherwise.

acted uponare kept out from the support n,

and within the plane of the movement of the shingle by springs p, as shown clearly in Fig. 3.

The operation of the machine is as follows The bolt, shown in red, and designated by P, is placed onthe carriage G, and motion is given the shaft B, by any proper s means. A reciprocating movement is given the knifeO, by means of the wheel c, on shaft B, and its fellow on shaft C, the two shafts B, C, rotating simultaneously in con'- sequence of the wheels V*05, a', gearing into i each other. A reciprocating movement is also given the carriage M, and upright N,

by means of the wheels c, on shaft B, and its fellow on shaft C, gearing alternately into the rack K, it being understood that the shafts B, C, rotate in reverse directions and' that the teeth on the wheels c, c', c, and b, Z9', b, are placed respectively in different positions in order'to give the reciprocating movement to the racks. The bolt is fed to the splitting knife O, in consequence of the arm I, acting against the teeth a", of the rack I-I, and the bolt is fed to the fence F, at each movement of the carriage G. The knife O, cuts a shingle from dicated by arrow 1. Vhen the shingle is rived from the bolt, the plate N, is moved in the direction of arrow 2, and shoves the the bolt as it is moved in the direction in-V in 1, order suit shin'fls' of different widths. The jaws z', z', of tie clamp K, receivethe end of the shingle, as it passes the joints o,` and the clamp as it moves back in the diseen that the Ashingles are rived from the block, cut in taper form and jointed at one operation, and by a very* simple arrange-` ment of means.

The fence F, not only serves the office of a stop but also serves toprevent the bolt from splitting out of line with the cut of the knife O, a contingency which frequently occurs provided the grain of the bolt vis not very straight. i j

Having thus described my invention what I claim as new and desire toA secure by Letters Patent, is,

Y 1. The employment or use'of the fence F, in combination with a reciprocating splitting knife O, and reciprocating or shoving plate N, arranged to operate substantially as and for the purpose set forth.

2. The reciprocating splitting knife O, shoving plate N, tapering knives E, E, jointers o, and clamp K,. combined and Yarranged to operate substantially as and for the purpose specified.

Operating the bolt carriage G, by means of the revolving Varm I, on'the shaft B, and the obliquely'toothed rack a", at the under side of the carriage Gr, substantially as described.
